A brief history of chemistry
By: Helena Whyte
Even though the Greek philosopher, Democritus, was the first person to say that matter is made up of very small, indivisible particles that he called atomos, John Dalton is considered the father of chemistry. John Dalton proposed the modern atomic theory in 1808. Investigators learned...
